8-x+7x=2.8
Add 7x to both sides.
8+6x=2.8
Combine -x and 7x to get 6x.
6x=2.8-8
Subtract 8 from both sides.
6x=-5.2
Subtract 8 from 2.8 to get -5.2.
x=\frac{-5.2}{6}
Divide both sides by 6.
x=\frac{-52}{60}
Expand \frac{-5.2}{6} by multiplying both numerator and the denominator by 10.
x=-\frac{13}{15}
Reduce the fraction \frac{-52}{60} to lowest terms by extracting and canceling out 4.
